Systems Of Equations
The thing systems of equations have in common
what is they share the same (x,y) value?
what is coordinate point (x,y) ?
what is the intersection point?
what is the solution?
The type of graph that has Q1, Median Q3 minimum and maximum
What is a box plot?
The form all linear equations must be in to graph
What is y = mx + b?
The definition of Systems of Equations
the buttons to press in order to enter an equation and graph
2. enter function
3. graph
The method of isolating one variable and replacing it with an expression that equals the variable
Example:
2y + 3x = 4
y = -4
2(-4) + 3x = 4
What is Substitution Method?
A high amount of Standard deviation means a high amount of this
What is variability?
2y = 4x - 8 in Slope intercept form
what is y = 2x - 4?
The definition of y - intercept
What is where the function crosses the y sxis?
Buttons we press to to see the table

1.2nd
2. graph
The method of solving systems where we add/subtract both systems from one another to get rid of one variable and solve for the other
Example:
2x + 3y = 12
+
-2x + 5y = 10
_______________
0 + 8y = 22
What is elimination method?
Tells us the middle point in the data
what is the median?
The slope of this equation:
y = 3x + 10
What is 3?
the definition of slope
what is the rate of change for the function?
When substituting a value, numbers should have these two things around it
What is parenthesis?
the operation you would use to eliminate a variable from this system
2x + -4y = 3
2x - 7y = 10
what is subtraction?
Tells us the average of all the data
What is the mean?
the y - intercept of this equation (coordinate point)
y = 2x + 4
what is (0,4)
Inverse operation
the opposite operation/ sign of the number
+4 = -4
3x = x/3
To move a value to the other side of an equation we must do this
What is inverse operation?
The operation you would use to solve this system of equation using elimination
-x + y = 4
-x + 2y = 8
what is SUBTRACTION
Standard Deviations tells us this
what is the difference between each data point?
Simplified version of this equation and the step you do to get there:
y = 2(4x - 12)
what is y = 8x - 24, distributive property?
Distributive Property
What is multiplying the number outside the parenthesis to every term inside the parenthesis?
